Merge "Members Online" and "Forum Statistics" sidebar blocks

I am trying to minimise the need to scroll up & down so much on my site, and to that end am trying to tidy up my sidebar.

Is it possible to merge the "Members Online Now" block with the "Forum Statistics" block? I currently use [bd] Widget Framework to present these in a tabbed block, but I would rather do away with the tabs and just display it like this:

...in the sidebar_online_users template, but it presented them as two separate blocks. I tried inserting the code insider the main div in aforementioned template, but it still presented them as two separate blocks, albeit with no space between them.

I thought I'd ask here as, even if I did manage to figure it out, I'm not sure I'd do it in the best/most compliant way (i.e. I might break something with a stray div, due to my lacking of coding skills), so I was hoping for a definitive answer from someone who knows their way round templates/styling/PHP!
